Missing Invites: If you fail to accept your invite then you will be immediately eliminated and your opponent will go through by default

12 Hour Rule: The person starting the game must either wait 12 hours or until his opponent posts an all-clear message before taking his turn. This is to promote fairness. Should the opponent advise me (before Turn 3) that the starting player has ignored this rule then the game will not count as a win to the starting player and will have to be played again.

This is a continuation of the It's a Knockout series, which carries a General Achievement medal for the series winner. That means it's advisable to join as many indiviual tournaments as possible as points will carry (one per tourney).
